Does Tesla and Comma AI etc classify based on adjacent frames, or does it choose what’s what one frame at a time?
I ask because the article mentions a flashing red light, which is common at rural intersections, and having a light flash is a proven way to grab a humans attention because we’re sensitive to the slightest change in brightness: think of a lost hiker flashing a mirror at a rescue plane overhead.
Without being sensitive to the blinking lights designed for humans, the car sees a floating red orb in one frame, and nothing in the next.
This quote from the Reuters article from yesterday makes me believe something about the tech stack makes it difficult to detect patterns of flashing light:
> In February 2020, Tesla's director of autonomous driving technology, Andrej Karpathy, identified a challenge for its Autopilot system: how to recognize when a parked police car's emergency flashing lights are turned on. "This is an example of a new task we would like to know about," Karpathy said at a conference.
